Signs you need fire rated sealant in Sand Hill
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
The most common problems we see are:
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
- Unsealed gaps where pipes and cables go through a wall
- Old fire sealant that has split or come away
Community buildings like Parish Church of St Andrew are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

How we handle fire rated sealant in Sand Hill
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on flats & HMOs, service penetrations and pipe & cable gaps, and common reasons people get in touch are door frames with gaps between frame and wall and ordinary sealant used where a fire-rated product was needed.
If you have holiday lets, a converted barn used for business or a community building near Sand Hill, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, large or small.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Somewhere like Sand Hill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.

Why it’s worth doing now in Sand Hill
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. In a small place like Sand Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

How the job changes by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.
Landlords, agents and businesses in Sand Hill
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
